ich brauche eure Hilfe. Muss den Spielbaum nochmal um eine neue Stufe erweitern und weiß nicht wie das geht.
Das ist mein 2-stufiger Spielbaum, der noch ergänzt werden muss:
\begin{figure}[htbp]
\begin{center}
% macro for inputing payoff vectors
\newcommand{\payoff}[4][below]{\node[#1]at(#2){$(#3,#4)$};}
\begin{tikzpicture}[scale=1,font=\footnotesize]
% Two node styles: solid and hollow
\tikzstyle{solid node}=[circle,draw,inner sep=1.2,fill=black];
\tikzstyle{hollow node}=[circle,draw,inner sep=1.2];
% Specify spacing for each level of the tree
\tikzstyle{level 1}=[level distance=15mm,sibling distance=55mm]
\tikzstyle{level 2}=[level distance=15mm,sibling distance=30mm]
\tikzstyle{level 3}=[level distance=15mm,sibling distance=15mm]
\tikzstyle{level 4}=[level distance=15mm,sibling distance=15mm]
